WRENCH.

, SPECIFICATION forming part of Letters Patent No. 783,071, dated February 21, 1905.

Application filed April 12, 1904.. Serial No. 202,850.

To all whom it may concern.-

Be it known that I, Mosns ENSIGN PoR- TER, a citizen of the United States, residing at Brigham city, in the county of Boxelder and State of Utah, have invented a new and useful Wench, of which the following is a specification.

This invention relates to wrenches of the class known as quick-action wrenches, and has for its object to improve and simplify the construction and produce a strong, durable, and inexpensive implement of this character, efficient in operation, easily and quickly applied, and which may be actuated by onehand only.

. \Vith these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its ad vantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of the invention and the claims made therefor.

In the drawings thus employed, Figure 1 is a longitudinal sectional elevation, and Fig. 2 is a front elevation.

The wrench comprises a stock 10, having the stationary jaw 11 at one end and provided with spaced ratchet-teeth 12 in one side disposed longitudinally of the stock. Slidable upon the stock is a movable jaw 13, having an integral sleeve 14 extending therefrom and inclosing the stock. Formed in one side of the sleeve 14 is a longitudinal recess 15, in which an elongated pawl 16 is pivoted at one end by a transverse pin 17 and with, ratchet-teeth 18 at the other end for engagement with the teeth 12 of the stock near the rear or lower side of the movable jaw 13. The movable jaw is provided with a recess 19, continuing the recess 15, and in which a projection 20 of the pawl 16 operates. By this means the outward movement of the pawl is limited and no danger exists of the pawl projecting unduly from the sleeve. The pawl is also provided with a loop 21 to receive the index-finger of the operator to assist in operating the pawl.

The aperture in the pawl 16 for the pivotpin 17 is elongated to permit acertain degree of longitudinal movement to the same and cause its extended end 20 to abut against the rear side of the movable jaw 13, and thus receive the strains and relieve the pin 17, which is thus required to bear the weight of the pawl only.

A pipe wrench jaw portion 23 may be formed upon the jaw portion 11 to coact with an opposing portion 24L upon the jaw member 13, and thus increase the efliciency and scope of the wrench.

By this arrangement it will be obvious that a very simply constructed and easily applied and operated wrench is produced which may be actuated entirely with one hand and in which the strains will be borne by the relatively heavy pawl and the more delicate and weaker parts relieved from the severe strains to which such implements are generally subjected.

A spring 25 will preferably be disposed between the stop projection 20 and the body of the wrench to maintain the pawl 16 yieldably in active position relative to the toothed stock.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A wrench comprising a toothed stock having a fixed jaw, a slidablc jaw carried by the stock and having a hand-grip embracing said stock, said grip being provided with an external longitudinal groove terminating at one end in a recess and provided with an opening intersecting the back of the groove and the opening into cooperative relation with the toothed portion of the stock, and a spring located within the recess to yieldably hold the toothed end of the pawl in engagement with the teeth of the stock.

2. A wrench comprising a toothed stock having afixed jaw, a slidable jaw mounted upon the stock and having a hand-grip embracing the same, said grip being provided with an external longitudinal groove terminating at opposite ends in recesses with an opening intersecting the back of the groove to expose the toothed portion of the stock at the inner recess, a pawl having a longitudinally-slotted terminal fitted in the outer recess of the groove with its inner end provided with teeth projected through the opening into engagement with the teeth of the stock and also provided with a finger-loop upon the outer side of the pawl, a pivot-pin piercing the slot of the pawl to permit endwise movement of the latter, and a spring located within the inner recess to yieldably hold the pawl in engagement with the stock.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
